Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 7 - 8; Mjukstrålar i ryggfenan (totalt) : 8 - 9; Taggstrålar i analfenan: 2; Mjukstrålar i analfenan: 8; Ryggkotor: 24. This species belonging to the S. tubulata group (with dark-dotted light organ) is distinguished by the following characters: D1 VII,9; pectoral-fin rays usually 12; tubed lateral-line scales 1-4 (usually 1-2); developed gill rakers of first gill arch 1 + 8-9; small serrae around angle of preopercle edge 8-15; light organ barely extending onto caudal peduncle, the extent 5.2–23.1 in caudal peduncle length. Colour in life generally translucent pale pinkish to reddish orange with a dense covering of variable-sized orange spots on head and anterior two-thirds of body; a prominent 'cat’s eye' black bar through eye, covering more than pupil at center, and flanked by white crescents covering remaining iris (Ref. .120588).
Found on sheltered reef slopes, the habitat consists of predominately Seriotopora hystrix coral colonies and small Acropora coral heads with close-set branches, providing shelter for groups of about 10-30 fish (Ref. 120588).
